Main Clair logic is changed in worker, updater, notifier for better adapting
ancestry schema. Extensions are updated with the new model and feature lister
and namespace detector drivers are able to specify the specific listers and
detectors used to process layer's content. InRange and GetFixedIn interfaces
are added to Version format for adapting ranged affected features and next
available fixed in in the future. Tests for worker, updater and extensions
are fixed.
HEAD of Alpine SecDB now uses one consistent schema for all of their
vulnerabilities, so the logic around parsing different versions can now
be removed. This change also crawls the directory structure to parse all
files due to the addition of community.yaml tracking community Alpine
Linux packages.
